[pmg-devel] [PATCH pmg-api 08/12] RuleCache: implement and/invert for when/from/to

[Dominik Csapak <d.csapak@proxmox.com>]

by introducing 'match_list_with_mode' that gets called for each group
and then on the result of each group match result.

This does not work for 'what' matches since they are not a simple
yes/no match (they include the parts) so this will be done seperately.
